STIMIPSON COMPANY, OF BROOKLYN, NEW YORK RIVETING MACHINE Application filed February 25, 1928. Serial No. 257,013.

This invention relates to rivet setting machines, and has for its object to increase the field of application for such machines and to facilitate their operation with large or cumbersome articles requiring considerable clearance below the anvil and on substantial- 1y all sides thereof.

Referring to the drawings:

Fig. 1 is the side elevation of one embodiment of this invention.

Fig. 2 is the front elevation of the device shown in Fig. 1.

Fig. 3 is the detail of the bracket and arm.

Fig. 4 is the side elevation of a modified construction embodying this invention.

Fig. 5 is a front view of the device shown in Fig. 4. i

Fig. 6 is the section on the line 66 of Fig. 4.

Fig. 7 is a side view of another embodiment of this invention.

Fig. 8 is the front view of the device of Fig. 7.

Fig. 9 is a detail showing the supporting bracket of Fig. 7.

An ordinary standard 10 is surmounted by a usual head 11 carrying the customary rivet feeding mechanism 13 and rivet setting mechanism 12. A usual form of anvil 14 is provided for cooperation with the mechanism 12. As shown in Figs. 1 and 2 the anvil is supported from the head 11 by means of a bracket 15 which includes a downwardly and outwardly extending arm and also a laterally and inwardly extending arm 17, these arms being secured together by bolts 16 or in any other manner desired. The connection between these arms is shown on an enlarged scale in Fig. 3 where the downwardly extending arm is shown as being grooved to receive the lateral arm 17 so as to pro vide a rigid foundation therefor, when the bolts 16 are in place. The arm 15 is preferably a casting while arm 17 should be of steel to give the requisite strength for the anvil. The anvil may be of any desired shape to suit the particular type of rivet be ing used and in the embodiment lllustrated, for example, in Fig. 3 the anvil is provlded with a raised portion 18. A lock-nut 19 adj'ustably secures the anvil in position on the arm 17 with the aid of the threaded member illustrated. The bracket 15 is secured to the head 11 in a manner to be described later in connection with Fig. 6.

Figs. 4 and 5 illustrate a modified form of the invention which forms the subject matter of my divisional application Serial N 0. 318,517, filed November 10, 1928, in which the bracket 21 extends to a greater distance below the anvil 24, there being a supporting column 23 interposed between the anvil and its lateral arm 22. The arm 22 is secured to the bracket arm 21 in the manner previously described in connection with Figs. 1 and 2. Having the bracket extend a considerable distance below the anvil provides increased clearance below the anvil on all of its sides. The bracket is preferably clamped to the horizontal portion of the head 11 as illustrated just below the pivot of the actuating lever 20 and as shown in Fig. 6

this connection is by means of bolts 26 passing through the head 11 and through the base of the bracket 21. For convenience in seat.- ing the bolt heads a spacing washer 27 is provided of a shape to conform to the outline of the head member 11. The aforementioned actuating lever 20 is pivoted above the head 11 within the bifurcated portion 25.

In Figs. 7 to 9 inclusive, the bracket 28 is secured to the head 11 in the same manner, but is much smaller and is provided with a relatively short lateral arm 29 supporting the anvil 30. As shown in Figs. 8 and 9 the vertical arm of the bracket is longer than either of its lateral arms and this form of the invention is useful where little clearance is necessary on one side of the anvil but a large amount is needed below the anvil on all sides or substantially so. This mechanism, of a supporting head therefor,

a standard carrying said head and mechanism, an anvil, and supporting means for said anvil extendlng laterally and down- Wardly from said head and provided with a lateral arm extending toward and supporting said anvil.

2. The combination with a rivet setting mechanism, of a supporting head therefor, a standard carrying said head and mechanism, an anvil, and supporting means for said anvil extending laterally downwardly and out wardly from said head to a position below said anvil and including a lateral arm secured to the lower portion of said means.

3. The combination with a rivet setting mechanism, of a supporting head therefor, a standard carrying said head and mechanism, an anvil, and supporting means for said anvil extending laterally downwardly and outwardly from said head to a position below said anvil and including a lateral arm secured to the lower portion of said means.

In testimony whereof I aflix iny signature.
